Horus, Who Transmigrates Across the Heavens

[Reborn and transmigrate + infinite worlds + steampunk + martial arts stat upgrades + Soulslike style] He was once the master of the Sixteenth Legion, the Empire’s Warmaster, and the man who personally ignited a war that burned across the galaxy. Even after his fall, Horus still remembered that golden figure. When he opened his eyes again, he found himself in an SSSS-rank high-risk world called Kowloon City. There were no Space Marines here, only mad invasions from other worlds, chaotic bio-modifications, and the brutal laws of the apocalypse. System: “I am the Paradise. Your identity is Guardian.” Horus: “What am I guarding?” System: “Everything you want to protect. But the price is… fighting your way through every world.” From the mountains of corpses and seas of blood beyond the portals, to the steampunk of the native worlds, to the fantasy invasions of higher-dimensional overlords. He is a tyrant, and a savior. He is the god of death, and a guardian deity. When his old comrades fall one by one in pools of blood, Horus finally understands why he was brought back to life. He no longer fights for his father, nor for ambition. He slings his rifle over his shoulder, shatters the void beneath his feet, and declares to the gods and demons of every world: “I returned from hell only to bring them home.” … [This is not fan fiction. The protagonist is a reincarnated Warmaster, intelligent, decisive, and unsentimental.]
